Trigger Source         GO BACK  Previous: Acquisition Mode   Next: Trigger Condition 

Trigger Source defines what signal is used to determine a trigger event.  Any time stream that is set as trigger source candidate in the CSA can be selected as trigger source on the CoCo-80. If a signal is not identified as a trigger source candidate in the CSA file then the signal will not appear on the list.  This feature is designed to simplify the user interface and optimize the CoCo-80 computation resources.

The candidates of Acquisition Mode selection and Trigger Source selection will be defined by the CSA editor. The CSA editor will assign some the data streams after the data conditioning as candidates of trigger sources. For example, in a CSA there are 8 channels, if you only select ch1 and ch2 time streams as candidates of trigger source and then this CSA will only show ch1 and ch2 on the trigger source selection menu.

You may also define time streams other than native channels as trigger source candidate. For example, if in the CSA an RMS measurement is derived from ch1, this RMS time stream can be used as a trigger source.
